如何在Laravel Blade的句子中始终显示5个单词（标签）

Question

After running a query, I get an array of results (articles) where each of them has their properties like id, name and tags.

This is the code where I display those values:

    @foreach ( $results['matches'] as $doc => $docinfo )
    ...
    {{$docinfo['attrs']['s_tags']}}
    @endforeach

But the problem is that some of articles have a long list of tags, for example:

"s_tags" => "Tech, geben, rasant, Wechsel, Pakete, Kunden, Details, Intel, Microsoft, Angebote, App, Web"

How can I assure that maximum 5 tags are displayed. So in this case it would be:

"Tech, geben, rasant, Wechsel, Pakete"

and of course, if there are articles with the number of tags less than 5, I want to display them all.

Answer 1

{{ collect(explode(', ', $docinfo['attrs']['s_tags']))->take(5)->implode(', ') }}

• Explode the string on , to turn it into an array
• Turn it into a collection with collect to get a fluent readable api
• Take at most 5 elements
• Implode it on , to get your comma delimited list back
